I actually drew the ref sheet back in December 2013. I had to finish it.
I've been considering having two sonas, since I'm a dude but my sona was still female, now I'll have two so depending on my mood i'll either draw the male or female.
The crows don't have much variety in them, but i believe the lack of boobs and narrower hips should be obvious.
The fact box is just a space filler I guess, no one will probably read the shitton of text on the ref sheet anyway.
